To @ZZ 'whom t 'may concern' lle known t l., Henny fie United residing at f o'i Marion and invent-ed certain 'zen ci; i ianenelis. in the cou' i lY .di iaa have usw: l improvements in Heat ln e; and Conveying' llevices 'for Furaces, eL which the following is a specification. l0 This invention relates to certain heat col-V lecting and conveying devices em connection with domestic heating` furnaces; and one oit the objects oit the invention is to intercept qnd retard dissipation oi" the born the Wells of the furnace said heat over the shortest nd discharge it into the leed lor i the temgect ot the invention, in adcepting and conveying' the 1rom the furnace Walls to the Uinge, is to maintain the norlici \ncy of the furnace., thereby f. minimum saving; in fuel with a.

ll'hilel certain advantages and benelicial results muy be obtained by the utilization ot my invention in connection 'with the rarious'types et' domestic heating furnaces on the market, l am sible to secure better re sults 'when the invention is employed in connection with that type ot furnace illusnloyed in Serial No. 552,569.

rated in the accomganying drawing, Wherein the external side Wells of the :furnace include laterally extending Wings or tins, and my invention will be hereinafter described in connection with that type o'f furnace.

Referring; to the nrawingse 10 represents the side Wall of the furnace., and ll the laterally extending' integral Wings or lins. l2 represents the outer CasinW which encloses the furnace proper and retards diffusion of the heated air. rlhe Wings or line 1l, which extend laterally from the furnace Wall l0, are comparatively thin so that they become easily heated end freely extract the heat frein the Wall and liberate same to the atmosnhere through their Wide expense of suraree. .along the exterior surface ot Wall l() and are preferably arranged a uniform distance. epa-rt, thereby providing' a plurality et ,intervening channels 13. These channels lf3 are utilized for installingmy invention, Which, as more clearly shown in 3 to l inclusive, consists of a plurality ot ei;- treniely thin metal sheets l5 each substantially L-shape in cross section, a number of which are brought toffe-ther to term' a section which may be bodily introduced into any one of the channels i3. its clearly shouui in 5, the material contiguous to one edge of each sheet 15 is bent at rigglit ang-les to form an outer Wall lea, after which the marginel edge of the metal ot the tree end of said Wall is bent to form a short-Wall 15b which stands parallel with the main Wall oit: sheet l5 and abuts t ie main Wall ot the severa-l sheets. breng; it together to torni a group lllhen a number of the bent sheets are brought together5 as illustrated in Fig. 3, they are held in proper relution by means of the tram ve,rse bolts i 17. As the trout uf'alls lf3 ot the .1s serve the purgmse 'of closing1 the open sides of the speces inte reningg' the sheets these end walls also serve the pu nose of maintaining? the spaced relation et' the outer end oi the sheets.

The inner ends of the sheets f1.5, next to W vll l0 ot the furnacey are held in sp ced relation by means et suitable collars 18 which are arranged on the transverse bolts 1G. ly means or" the herein shown arrangement et a number of independent sheets l5 into a group or section l am able to secure a number of nthe'adjacent spleet j wheny The tins ll extend vertically' S0 wards wall 10 of the furnace, and the ends terna] passagcimys 2t) whichv are adapted to intercept andY prevent rapid diffusion .of the heat radiated both from the furnace wall l() and ,thev walls of ysheets l5, and to convey and discharge said. heated air into.

the pipes 22 leading to the ioonisof the building. its best shown inlfig. l, the several groups, eacli'comprising a number of individual bent sheets l5, extend some distance above the tcp of the inner furnacespeedily and in a directline to said pipes 22 with a minimum reduction inthe temperature of said air.

sheets are made of comparatively thin metal so as to reduce the weight of each group to a minimum, thereby facilitating their installation and disassemblement froml the furnace. Each group, constituting the present invention, may be removably remounted in operative position by attaching the ribs 25 to the side walls and near the free edges of the wings 11. The ribs 25 of the transversel bolts 17 are sufficiently exl tended to rest upon and be supported by a pair of therib's 25. Hence, when one group is placed into operative position it will move .inwardly by gravity until the free ends of the sheets abut the external surface of wall l0 of the furnace. l prefer to employ twokv y of the group, so as to4 hold both ends of each f group constantly into contact with the side wall of the furnace. j

rlhe foregoing description is merely illustrative of the principles of my invention, and other modifications thereof may be made that will function in substantially the same lmanner without. departing from the spirit `of the invention, and l do not, therefore, desire to limit myself to the use of any specific form of the parts illustrated.

Having thus fully described iny said iii.- vention, `what l desire to secuieby .letters Patent, is

Il. The combination with a hot air furnace, of. a plurality of sections for forming iassageways for receiving and 'conveying heat radiated from the/furnace wall, each vsection being substantially L-shape in crossytions in operative positioii.`

iaaofise section the integral right angular extension on the outer end of each section extending` to the next adjacent section foi'forming a closure lengthwise of the sections the free end of each right angular extension resting against the face of the next succeeding section and terniinatingshort of the forward end of the succeeding section, and means for connecting the ksections in assembled formation.

2. rlhe combination withv a het air furnace, of avplurality-of'nietal sections for forming heat conveying 'passageways exteriorly ofv and adjacent to the furnace wall, an integral right `angular extensionat they outer end of each section extending into en-` gageinent with the adjacent section forv As will be readily observed, the individuall forming a closure lengthwise of the sections7 the free end of the right angular extension being bent inwardly and lying parallel withthe side face of the adjacentsection, and means for locking the sections in assembled formation. l v

3.r ln combination with a hot furnace,

means consisting of anumber of independ- Y entlyformed sections providing a plurality of air -conducting passageways arranged along the external surfaceof 4the furnace wall for conductingv the intercepted heat radiated from the furnace in a direct'path of travel to the furnace outlet openings,` means for fastening the sections together,ribs on said furnace and means on the air conducting passageways for engagement with said. ribs, lsaid ribs being inclinedtowards the furnace whereby tlie'secticns will be moved by gravity towards the wall of the furnace.l

t. ln combination with a hot air furnace having outwardly extending fins formin channels, of means comprising sections a ranged in said channelsand having passageways foi' receiving and conducting the intercepted heat radiated frointhe furnace y to the air outlet openings'of the furnace.

5. ln combination with a hot air furnace.:

having outwardlyv extending fins' forming channels, of meai'is'comprising sections arj vthe air outlet openings of the furnace, and

means for removably mounting `said secj vIn witness whereof, l have hereunto set inv hand and sealat Indianapolis, indiana,
